Question

Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.

Answer 2

Answer:

Here is a list of talking points I can use — I did come up with a few tips that homeowners can do to help prevent shallow slides:

• Landslides in the Puget Sound area normally occur during the months of January and February, after the ground gets saturated from winter rains.

• Slides are caused by water, gravity and generally a layer of clay that lets loose.

• If the record rains of October continue (and for 2016 Washington is 10” of rain above normal) then we could have problems.

• The best way to avoid landslides is not to live or work in an area that has a landslide history.

• Seattle has over a 100-year history of mapping where landslides have occurred. The Seattle Office of Emergency Management has a hazard map that includes landslides as one hazard.

o Avoid those hazard areas.

o Those million-dollar views can sometimes be very expensive.

• Land movement is not covered by the normal homeowners policy. Those special hazard policies are very expensive. Lloyds of London is one of the few who offers policies.

• To prevent shallow slides, you can do a few things on slopes that are on your property:

1. Maintain as much vegetation as possible on the slope to help retain the soil.

2. Do not put yard waste on the slope.

3. Do not add additional water from downspouts to slopes from storm water runoff being directed to a hillside.

4. Do not have an irrigation system on a hillside.

5. Don’t locate swimming pools near a slope.
